Got the barrel and immediately started testing to see if it was anymore accurate... The Result... Eh...

Pros: Barrel looks beautiful off of your TPX or other A5 Threaded Gun, Rifling, Slightly more accurate than stock.

Cons: Not Spiral rifling. Still short, not a major improvement over stock, at least in my impromptu tests.

Other Thoughts: This barrel is a great price, for a new barrel. It's the same length as the stock barrel, and improves accuracy slightly, but not by leaps and bounds. Frostbite tip is threaded, so can be ported to a different barrel. Didn't seem to make that much of a difference to me and my groupings.

The rifling in the barrel, is not standard rifling. It's got some guide-line type indents, but no true spiral-rifling like in the HammerHead Barrel.

(However, there is a possibility I may have been using inferior paint. Inferior but not quite Wal-Mart...)
